Guangyang bearing normal maintenance to avoid failure two ways

The first thing to emphasize is that it is important to keep the bearings lubricated and clean. Therefore, before we inspect the Guangyang bearing, we should clean the surface of the bearing and then remove the parts around the bearing. It should be noted that the oil seal is a very fragile part. This requires extra care during inspection and disassembly. Do not apply excessive force to avoid damage to the parts. Then carefully check the bearing's oil seal and its surrounding parts. If it has been shown to be a bad symptom, be sure to replace it. A bad oil seal will cause damage, causing the bearing cloud to be abnormal and causing the machine to stop.

Secondly, we also check the lubricant of Guangyang Bearing. Lubrication is very important, not only for bearings, but also for all bearings. However, please note that it is not advisable to add too much grease to the bearings. The inspection method for the bearing lubricant is: rubbing a little lubricant between the two fingers, if there is a contaminant, it can be felt; or apply a thin layer of lubricant on the back of the hand, and then seal the light. Then it is to replace the lubricant of the bearing. Bearings lubricated with oil should be refilled with fresh oil and allowed to rotate at low speed for a few minutes if the old oil is drained. As much as possible, allow the oil to collect the contaminants from the wreckage and then vent the oil. Note: It is best to filter the oil before use. For bearings that use grease-lubricated bearings, the replacement of the grease should be avoided with a cotton joint to any part of the bearing. Since these residual fibers may be wedged between the rolling elements and cause damage, especially the application of small bearings requires attention to this problem.

Finally, it is important to note that the exposed bearings are covered. When inspecting bearings, never expose the bearings to contaminants or moisture. If the work is interrupted, the machine should be covered with a piece of oil-paper plastic or similar material. If the unshielded bearing is cleaned without the possibility of disassembly, the brush for application should be cleaned with a petroleum solvent (whitespirit), then dried with a lint-free cloth or blown dry with compressed air ( Be careful not to let the bearing assembly start to rotate). Check the track faces, retainers and beads of the bearing with a small mirror and a probe similar to that used by dentists. Do not clean the bearing with a sealing cover or dustproof; just wipe the outer surface. If the bearing is damaged, it needs to be replaced.

INA outer spherical bearing lubricants to solve the problem

INA bearing will change its bearing capacity, rotation precision and wear resistance due to its own quality and external conditions during use. When the performance index of the outer spherical bearing is lower than the use requirements and cannot work normally, the bearing will occur. If the fault occurs or even fails, the machine and equipment will stop and there will be various abnormal phenomena such as loss of function in case of failure of the bearing, etc. Therefore, it is necessary to find out the cause in a short period of time and take corresponding measures.

In order to maintain the bearing under good conditions, it should maintain its proper performance and long-term use. Bearings must be inspected and maintained. Inspection and maintenance are important to prevent malfunctions. During operation, it is important to check the rolling noise, vibration, temperature and lubricant of the bearings.

Under the conditions of high speed and high temperature, the adjustment scheme of the combined position and clearance of the outer spherical bearing can be oil lubricated when the grease lubrication is not suitable. A large amount of heat can be taken away by the circulation of the lubricating oil. Viscosity is an important characteristic of lubricating oil. The viscosity directly affects the fluidity of lubricating oil and the thickness of oil film formed between friction surfaces. The viscosity of lubricating oil at INA bearing working temperature is generally 12-15cst. The higher the speed, the lower the viscosity, and the heavier the load, the higher the viscosity. Commonly used lubricating oils include mechanical oil, high-speed mechanical oil, turbine oil, compressor oil, transformer oil, cylinder oil, and the like.

Oil lubrication methods include:

a. oil bath lubrication

Oil bath lubrication is the most common lubrication method. It is suitable for the lubrication of low and medium speed bearings. Part of the bearing is immersed in the groove. The lubricating oil is brought up by the rotating bearing parts and then flows back to the oil groove. The oil level should be slightly lower than the minimum. The center of the rolling element.

b. drip lubrication

Drip lubrication is suitable for the outer spherical bearing parts that need to be quantitatively supplied with lubricating oil. Considering the structural design of the bearing supporting parts during thermal expansion, the amount of dripping is generally one drop every 3-8 seconds, and excessive oil quantity will cause the bearing temperature to increase.

c. Circulating oil lubrication

The filtered oil is delivered to the bearing components by an oil pump, filtered through the lubricating oil after the bearings, and then cooled and used. Since the circulating oil can take away a certain amount of heat and cool the bearing, this method is suitable for INA bearing parts with high speed.

d. Spray lubrication

The dry compressed air is mixed with the lubricating oil through a sprayer to form an oil mist. In the jet bearing, the air flow can effectively cool the outer spherical bearing and prevent the intrusion of impurities. This method is suitable for the lubrication of high speed, high temperature bearing components.
